This invention relates to apparatus for impregnatin parts of an absorbent'mass with a liquid:

This application is a continuation in part 5 of'my previous application filed October 7,

1922, Serial No. 592,964 (on which U. S. Patent No. 1,456,344 was issued to me on May 22, 1923) in so far as it embodies the disclosure of said application. In that application I described a. method of dyeing textiles, apparatus for carrying out said method, and articles of manufacture produced thereby.

723,430, filed June 30, 1924, as a division of the present application.

A feature of the invention is to provide apparatus for injecting, under pressure, a

limited quantity of liquid into an absorbent mass so .as to form a stream of the liquid extending into the mass and to arrange this apparatus so that this streamof dye may be free to expand laterally throughout its length by absorption into the pores of the mass. Y

ner by a plurality of injections of dye into the mass. The invention includes, also,

means for varying the relative positions of a holder for the mass of yarn and an injecting apparatus, which may be used tocarry out this method.

In order that the invention may clearly be understood, I will describe in detail a practical yarn-dyeing machine embodyin a combination of all the apparatus features of the invention to which. reference has been made, as well as additional features hereinafternoted. Such a machine is illustrated 1n the accompanying drawings, in which Fig. 1 is a plan view of the machine:

Fig. 9 is a perspective view of the clutch which holds the needle of the injector;

; Fig. 10 is a perspective view of the needle;

Figs. Y11 and 12 arev side views of acone drawings comprises a base plate B, on which are mounted a dye tank T, a pump P and a work holder W. In the use of the machine, a cone C of yarn 'is supported on the work holder W, and measured quantities of liquid dye from the tank T are forced into the cone by the pump P through an injector J, which is mounted on the cylinder of the pump.

The pump P has a cylinder P, which has at its lower end a flange P which is bolted to the base plate B. The lower portion of the cylinder P serves vmerely as a su port for the operative arts of the pump an contains a large axlal bore P to reduce 1ts {weight The upper portion of the pump cylinder P? contains a smaller axial bore, the lower end of which is closed by a plug P. The portion of the smaller-bore above the plug P provides a chamber P into which liquid dye flows from the tank T and from which measured quantities of the dye are expelled under pressure. The chamber P is provided with an inlet opening P, an air vent opening P and a discharge openlng P The outer end of the inlet opening P is connected by a pipe P with an opening T near the bottom of the tank T. The outer end of the opening P" communicates with an open vent pipe P The discharge opening P communicates with apparatus J for directing liquid dye into a mass of yarn supported on the work holder W. This apparatus, which for the sake of brevity, I term an injector, is hereinafter described in detail. An opening P in the cylinder wall near the lower end of the chamber P places this chamber in communication with a closed compression chamber P. In the form illustrated, the compression chamber 1 is formed by an elbow pipe P and a pressure gauge P of ordinary construction, which serves to close the outer end of the pipe P.

The inlet opening P", the air vent opening P and the discharge opening P are controlled by a valve sleeve P containing ports P P" and P which register with these openings respectively in certain positions of the valve sleeve. The valve sleeve is thrust upward by a compression spring P reacting between the lower end of the sleeve and the plug P. A pin P projecting through the wall of the cylinder P into a longitudinal slot P in the valve sleeve prevents turning of the sleeve and limits the upward movement of the sleeve under the thrust of the spring P". A plu P is secured in the upper end of the va ve sleeve 1?. This .plug normally projects above the top surface P of the cylinder P and has at 1ts upper end a cam surface P.

The plunger P of the pump fits within the valve sleeve P. The plunger is mounted on a rod P whichextends through the plunger. The lower end of this rod enters an axial bore P formed in an axial extension P of the plug P. The upper end of the rod P passes through an axial bore in the plug P and normally projects beyond the upper end of this plug. The rod has at its upper end a cam surface P Rotation of the plunger rod P in the sleeve P is prevented by a key P fixed in the rod and engaging a key-Way P in the plug P. The plunger P is thrust upward by a compression spring I surrounding the lower portion of the rod P and reacting between the lower end of the plunger and the upper end of the axial projection P of the plug P.

The valve sleeve and the plunger of the pump are operated by means of a double cam P? providing a central cam surface P which engages thecam surface P at the upper end of the plunger rod P and two spaced cam surfaces P which engage the cam surface P of the upper end of the plug P which is fixed in the valve sleeve P. The cam P is fixed on a shaft P, which is rotatably mounted in two ears P which extend upwardly from the upper end,

of the cylinder P The shaft P and the cam P may be turned about their axes by means of an operating lever P which may be formed integral with the cam P, as shown.

In operating the pump, the operating lever P is oscillated between its raised position shown in Fig. 6 and a lowered position in which a projection P on the cam P engages the cylinder P at P. The downward movement of the lever may be caused manually, while its return or upward movement is most desirably caused by a spring. I find that the most convenient way to provide for theoperation of the lever P is to connect it to a foot pedal of usual construction located under a table on which the base plate of the machine is supported. Such a pedal is indicated diagrammatically at P in Fig. 1. The return movement of the lever P may be caused by the usual springreturn mechanism used with foot pedals. A spring for causing the return movement is diagrammatically illustrated at P in Fig. 1.

The operation of the pump is as follows:

When the operating lever P is in raised position, the cam P, the valve sleeve I and the plunger P occupy the positions shown in Figs. 6 and 8. The valve ports P and P" register with the inlet opening P and the air vent P, respectively, so that liquid dye flows .by gravity from the tank T into the chamber P and fills the chamber. During the filling, the air which was containedin the chamber escapes through the vent pipe P During the first part of the downward movement of the operating lever P, the

cam surfaces P enan'd depresses the sleeve P while the portion P of the cam 1 surface P engages the cam surface P and depresses the plunger P The downward movement ofthe plunger is a little more rapid than that of the sleeve. The initial do ward movement of the sleeve closes the ililetopening P and the air vent opening P, and as soon as this occurs the downward movement of the plunger forces a portion of the liquid dye confined in the chamber P into the lower part ofthe compression chamber P compressing the air trapped therein. The liquid dye in the chamber P is, therefore, placed under an increasing pressure as the plunger descends. When the sharply inclined port-Ion P of the cam surfaces P engages the cam surface P, the sleeve P is givena sudden short downward movement which brings its port P into register'with the discharge opening P thus opening the discharge opening instantaneously. The downward movement of the sleeve then ceases, owing to the fact that the portion P of the cam surfaces 1? is concentric with the shaft P. The downward movement of the plunger continues after the sleeve has stopped and becomes very rapid, owing to the inclinationf of the portion P of the cam surface P On the opening of the discharge opening P liquid is ejected from the chamber P by the pressure stored in the compression chamber P The pressure on the liquid is maintained during its discharge by the final rapid descending movement of the plunger. As a result, a measured quantity of liquid, that is, the amount displaced by the movement of'the plunger, is ejected from the chamber 1 under pressure and almost insta-ntaneously.

Du the return or upward movement of the operating lever 1 P, the described movements of the phmger and sleeve are reversed.

The initial rapid upward movement of the plunger, while the sleeve remains stationary with its port {P in register with the discharge openii'ig P causes an. inward suc tion through the discharge opening. \Vhen the upward movement of the lever is completed, the plunger and sleeveare again 1n filling position.

The movement of the operating lever P offthe pump is utilized to stir the dye in the tank T- S0 as to prevent aseparatlon of transferred to the the ingredients of the dye. For this purpose, a stirrer consisting of a propeller T is placed in thetan'k T. The'hub T of the 'stirreris rotatablymounted on a vertical the shaft T in one direction tothe P by the operating lever P are transferre to the shaft T The rotation'of the shaft T which is caused on downward movements of the operating lever P ispropeller by means of the ratchet T 011 upward movements of; the lever P, the ratchet T slips under the ratchetteeth'of the propeller hub T so that the propeller does not retard-the upward movement of the operating lever and the parts connected with it.

Apparatus is limited quantities of liquid -which ejected from the pumpinto a mass of yarn supported on the work holder. Such apparatus I have, for the sake of brevity, termed an ejector. It may consist merely of a nozzle, by which term I designate any device providing a discharge opening for directing liquid in a predetermined direction. A feature of the invention consists, however, in forming the injector so that it opens a narrow passage into the mass and directs the liquid into the mass through this passage. In order that the mass may be dyed evenly throughout all or aconsiderable portionof its depth, the injector is formed to permit lateral expansion of the shaft of liquid in-- jected into the mass throughout the depth of the injection. .The injector is formed also toprevent the liquid from spreading over the surface of the mass around the poi t at which it is injected.

In the form illustrated in Fig s.'8, 9 and 10, the injector J comprises a nozzle J and a. needle J fixed in the dischargeopening of the nozzle. The nozzle J has a body J on the rear end of which is a threaded stem J which is screwed into a tapped hole P in the cylinder: PM This hole P communicates with the discharge opening P but is not co-axial therewith. The projection J contains an axial bore J", which is the intake opening of the nozzle J The central portion of the body J 3 of the nozzle provides are provided for directing the Y a flange J whichis seated against the boss front end of the body and engages the chuck the body J is'locontaining an axial bore flat 'contact surface J 14 which is thrust when the massv is brought into operative,

against the surface of the mass to be dyed relation with the inj ector. On the outer end of'the nut Jl is a stop. J providing an anthe axial bore J v of the chuck J I nular-surface J lying insubstantially the 10 same plane as the contact surface J and spaced therefrom;

The needle J 2 'has its rear end inserted in It is retained in the chuck by contracting the chuck by screwing the nut J inward. As the shaft ofthe needle is of uniform diameter,

it may be gripped'at any point by the chuck. It follows that the distance which the needle projects beyond the contact surface J may be adjusted, and that-after an ad ustment is :,j1nade and the nut J isscrewed in tightly, the needle is held in fixed relation to th s -contact; surface. The fact that the hole P is not co-axial with the dischargeopening P so. that the intakeiopening J of the nozzle is not in alignment with this opening, eliminates all danger of bringing the needle into "contact with the sleeve l by thrusting'its rear end too farinward.

' the apex of Which'is on the axis of the The needle J 2 has a pointed front-end J needle. The needle is formed to provide a longitudinal passage J which extends substantially.. its entirev length and communicates with the discharge opening J of the nozzle. The needle is formed to permit lateral egress from this passage throughout substantially the entire length of the projecting portion of the-needle. of injector shown'in-Figs. 8 and 10, such In the form ec'ress is permitted'byi giving the longitudinal fpas'sage J the form of an open groove. Provision for lateral egress of the liquid in a needle'having' an axial longitudinal passage such as the needle J shown in Figs. 15 and 16 is made by providing a plurality of lateral openings J inthe wall I "the mass in makin of the axialpassage J".',: In such case the lateral openings'J? are positioned all along the portion of the needle which is thrust into an injection.

A feature of the invention consists in v ".turning the"open side .of the groove J of the needle J in such direction that the strands of the mass into which the needle is thrust are not drawn tlghtly over the groove so asto'objstruct the egress of liquid there- I. .from. To accomplish this purpose, the open side of 'the groove J isturned in a direction as nearly asipossible parallel to the lay or lays of the yarn in the mass to be impregnated, or, in other Words, by turning the needle so that the groove lies in a transverse plane of the wound mass of yarn. As the work holder W of the-machine illustrated, which is hereinafter described in detail, is adapted to hold the core of a wound mass of yarn with its aixis horizontal, the needle J 2 is secured in the chuck J in such manner that the open side of the groove J is turned either directly up, as shown in the drawing, or directly down.

Means are provided for preventing the liquid which is forced into the injector from spreading over the surface of the mass into which it is to be injected. In the form of injector shown in Fig. 8, the contact surface 1% atthe outer end of the nozzle serves this purpose when it is pressed firmly against the surface of the mass.

The modified injectors J and J", shown in Figs. 14 and 15, respectively, are not formed. to provide contact surfaces similar to the contact surface J but embody a different means for preventing the liquid from spreading over the surface of the mass. The needle J shown in Fig. 14, has a longitudinal passage which consists of an open groove J extending the greater part of of greater cross-section than the open groove.

When aninjection is made with the injector J, the needle J is thrust into the mass to such an extent that the closed passage J extends slightly inside the surface C of the mass (indicated by a dotted line in Fig. 14). When the needle is in this relation to the mass, the walls of the closed passage J serve to prevent a spreading of the liquid over the surface of the mass.

The needle J shown in Fig. 15, is similar to the needle J except that the open groove J is replaced by an axial passage J provided with a plurality of lateral openings J \Vhen an injection is made with the injector J", the needle J is thrust into the mass to such an extent that the rearmost of the openings .1 is within the surface C of the mass.

Specific features of the modified injector shown in Fig. 15 are not claimed herein, as they form subject-matter of my divisional application filed December 30, 1925, Serial No. 78,323.

. The work holder V is adapted to support a wound mass of yarn for movement towards" and away from the injector to bring the mass into and out of operative relation to the injector. These movements are in directions parallel to the axis of the injector, i. e., of its discharge opening J, and consequently parallel to the needle J. of the injector. The work holder also permits movements of the surface of the mass in directions transverse to the needle J so that different points of the surface of the mass may I be brought opposite the injector. Means are provided for arresting the latter rasse To support such a cone, the work holder V, is provided with a shaft W, on one end of which is an expansion clutch W ada ted to grip the hollow core C of a cone yarn and to hold the cone coaxial with the shaft. The clutch W is operated by a lever W connected with it by a push rod W lying in an axial bore in the shaft W.

The shaft W is mounted so that its axis and the axis of the cone C lie in the same horizontal plane as the needle J Theshaft. is inclined to the needle at such an angle that the cones surface G which is towards the injector, is substantially perpendicular to the needle J In order to provide for movement of the cone towardsv and away from the injector, the plate W is slidably mounted on two bars W", which extend parallel to the needle J The bars W are mounted on a frame W which is mounted on the base plate B of the machine in the mannerhereinafterdescribed. A lever W is provided for causing sliding movements of the plate W on the bars W. This lever is pivoted at W to a cross piece W secured to the ends of the bars IV" and has a pin and slot connection with an arm W extending from the outer end of the plate W". An adjustable stop W is provided for limiting inward movements of the plate W. This stop is set to prevent the plate W from moving inward to an extent suflicient, to bring the point J of the needle J 2 into contact with the shaft W or the clutch W as such con-\ tact would injure the point on the needle. The stop W is, however, not used to arrest the inward movements of the plate W in the ordinary operation of the machine, as the stop J accomplishes this purpose.

The work holder permit-s movements of the surface. of the cone 0 in directions perpendicular to the needle J Two movements of this sort are provided for. One is a bodily movement of the cone in the direction of theside C of the cone which is adjacent to the injector. Such movement is provided by mounting the frame'W which carries the bars W, so that it may slide shaft at predetermined points.

across the base plate B of the machine. For this purpose, the frame W is mounted on two cross barsW? and VV", whose ends are held in projections B formed on the upper surface of the base plate B. The frame W may be slid along these bars by means of a lever WV" which is pivoted to the base plate B at W and has a slot and pin connection with the frame WV at W. In order to arrestthe sliding movement of the frame W? at predetermined points, the cross bar IV" is provided with recesses W and W and the frame W? carries a springpressed plunger W having a pointed end adapted to enter either of these recesses. The cross bar W is held against longitudinal movement on the base plate B by a set screw W By loosening this screw, the longitudinal position of the barmay be adjusted to vary the positions in which the motion of the frame W is arrested by the The shaft W is mounted on a standard W, which projects up from a plate W". I

means described.

cone C is permitted by mounting the shaft W on the standard W in such manner that the shaft is free to rotate. Means are provided for arresting rotary movement of the For this A further movement of the surface of the I purpose, a guide wheel W is mounted on the shaft W near its outer end. The guide wheel 'W is detachably fixed on the shaft by means of a set screw W. The guide wheel has an outer cylindrical surface con-.'

taining a groove W. In this groove are depressions W On an arm W project-*-v ing horizontally from the ported a spring-pressed engages the groove'lV of the guide wheel W. The ball W is seated at the upper end of a vertical bore W in the arm W and urged upwardly by a spring-pressed plunger W A pin W on a plug W plate W is supall V which, 2

screwed into the lower end of the bore W 7 serves to limit the downward movement of the ball so as to prevent it from slipping out of the groove NV". The ball is given suflicient freedom of vertical movement to enable it to enter and move out of the depressions l A feature of the invention, which is not claimed herein as it forms the subject matter. of my divisional application filed. December 30, 1925, Serial No. 78,322, consists in a method for obtaining long spots on' a yarn by injecting dye into a mass of the yarn wound in any regular manner. A yarn having spots whose length-is no greater than the width of the portion of a mass of the yarn which may be dyed by a single injection of dye may, by means of certain types of knitting machines, be formed into a fabric having an attractive mixed appearance. I have found, however, that when other types of knitting machines are used, it is neces- 'sary, in order to produce an attractive fabric, that the spots on the yarn be several inches in length.

My method of obtaining long spots consists in injecting dye into a wound mass of the yarn at a series of points lying along a lay of the yarn and separated by such distances that the portion of the mass dyed by the injection at onepoint contacts with, but does not materially overlap, the portion of the mass dyed b the injection at the next point. In app ying this method to cross-wound cones of yarn, I make injections at each point of several different series of points and locate the points of one series along one lay of the yarn of the cone and the points of another series along another lay of the yarn of the cone. \Vhen a cone of yarn which has been dyed by this method is unwound, it is found that long spots have been formed on the yarn.

A further feature of the invention, embodied in the machine illustrated, consists in providinga work holder adapted for use in carrying out this method of dyeing. For this purpose, the shaft W is mounted on the standard V in such manner that it is free to move axially as well as to turn about its axis, and the groove W in the guide wheel V is formed to provide a plurality of helical portions which extend parallel to the lays ofthe yarn of the cone. In the form illustrated, the groove W has two helical portions WV, W parallel to one lay of the yarn and one helical portion "W parallel to the other lay of the yarn. The ends of these three helical portions of the groove are spaced from each other, and are joined by connecting portions W so that the groove WV extends all the Way around the circumference of the guide wheel. The depressions W are spaced regularly along each of the helical portions W', TV, TV of the groove, while the. connecting portions W of the groove contain no depressions.

The use of the machine which has been described is as follows:

A cone C of the yarn to be spotted is first placed on the work holder ,W. This is done when the lever VV" is thrown to the right, as shown in Fig. 1, so that the shaft W is as far as possible from the needle J The hollow core G on which a cone C of yarn is wound, is slipped over the clutch W while the lever W is turned out to permit contraction of the clutch W. The lever 1V is thrown into the position shown in Fig. 3 to expand the clutch and lock thev core on the shaft W The levet W is then thrown to the left, moving the cone 0 towards the injector J and causing the needle J to penetrate the -cone of yarn in a direction perpendicular to the cones surface C which is opposite the injector. The movement of the cone of yarn and the plate W is arrested when the surface C of the cone C comes in contact with the surface J of the stop J As the mass of yarn is compressible, the plate W is not brought to rest until the part of the 1 mass which is brought against the stop J is somewhat compressed, as shown by the injured if its point is forced into the core to some extent. 1

A measured quantity of liquid dye is then injected into the cone of yarnby depressing the pump lever P. The injected dye pens-- trates to the core C of the cone before any substantial part of it is absorbed into the pores of the yarn. The injection thus results in forming a shaft of dye extending into the cone of yarn in the passage opened by the needle J This shaft of dye then spreads, by absorption, into the portion of the cone adjacent to the needle throughout the length of the shaft of dye injected. The portion of the cone colored by the dye is approximately cylindrical in shape and extends from the outer surface of the cone to the core in a direction perpendicular to a plane tangent to the outer surface at the point where the injection is made. The dyed portion is of substantially the same cross sectional area throughout its depth.

The pump lever P is released as soon as it has been pressed all the way down. During the upward movement of the lever, any liquid dye which may remain in the nozzle or the needle of the injector is sucked back into the pump chamber P so that this dye does not soak into the yarn and cause irregularities in the coloring.

The lever W is then thrown to the right, moving the cone of yarn away from the injector so that the needle is withdrawn from and the lever P are then repeated so that another portion of the cone of yarn is dyed.

The guide wheel W is turned so as to bring the ball W successively into each of the depressions W, and after each -turning of the wheel another injection is made in the manner already described. The lever W" is then moved so as to shift the frame W along the cross bars W and W If durea set ing the first'series of injections the frame W was set with the plunger W in the recess 7*; it is now moved to brlng the plunger into the recess ;'or if the plunger was firstaiin the recess W, the frame W is now moved to'bring it into the recess W The guide wheel W is again turned to bring the ball W into each of the depressions W successively, and in each pos1t1on of the guide wheel another injection is made. This com letes the spotting of the yarn of the cone 8, which may then be removed and replaced by a fresh one.

The result of the operation described may best be understood from the development of the outer surface of the cone C, which is shown in Fig. 13. In that view, the points of the surfaceof the cone from which Injections have been made are indicated by dotted circles. Injections were made at three series of points a, b, a, while the plunger was in contact with the recess W. These three series of points correspond to the depressions W in the three helical portions WV, W, W of the groove W. The points of the seriesa and I) lie along one lay of the yarn and the polnts of the series 0 along the other lay of the yarn. In ections have been made at three similar series of points a, b, 0', while the plunger W was in contact with the recess W As a result of the injections at these points, six portions of the cone of yarn have been dyed. Each of the dyed portions D is long and comparatively narrow and extends in the direction of one of the lays of the yarn, as best seen in the side views, Figs. 11 and 12. Each dyed portion extends from the outer surface of the cone C to its inner surface (i. e.,

its surface in contact with the core C in a Y direction inclined to the axis of the cone and perpendicular to a plane tangent to the outer surface of the cone at the outer end of the dyed portion. The sides D of eachdyed portion are approximately straight, as seen in Fig. 3, and the ends of each dyed portion are also substantiallyv straight, so that the area of each dyed portion. is substantially .uniform throughout the depth the yarn of the cone.

A cone of yarn dyed in this manner is a new article of manufacture which forms a part of my invention, which is not claimed herein as it forms the subject matter of my divisional application filed June 30, 1924, Serial No. 723,430. When such a cone is unwound, the yarn is found to contain longv spots where it extended longitudinally throughone of the dyed portions D of the cone, and intermediate short spots where it extended transversely across one of these dyed portions of the cone. When such a yarn is made into fabric, it produces a mixture of attractive appearance.

Among the advantages of the machine which has been describedis its adjustabilitywhich enables it to operate upon differently wound cones of yarn. To adjust the machine for cones of different depths, it is merely necessary 'to loosen the nut J and vary the longitudinal position of the needle J 2 in the chuck J Adjustments for variations in the longitudinal position of cones on their cores may be made by loosening the set screw W and varying the longitudinal position of the bar W and its recesses W, W.

In order to adjustthe machine for the variations in the angles of the lays of the yarn on cones wound on'difi'erent machines, or on differently adjusted machines, the set screw is loosened and the guide wheel Vi is removed from the shaft W and replaced by a guide wheel having a groove with portions that correspond to the lay of the yarn on the new cone. guide wheels may be supplied with'the machine for positioning a cone to produce any predetermined arrangement of the portions dyed. In this way, the position and extent of the dyed portions of a cone may be so predetermined in accordance with the winding of the cone and the manner in which the yarn is to be knitted or otherwise formed into fabric that, under any conditionsof winding and knitting, a fabric of a desired appearance may be obtained.
